使用API阅读来自Blogger的公开帖子

我已经编写了一些简单的代码，用于使用我的Twitter开发人员密钥和秘密从公共时间轴读取tweet。这样我就可以在用户自己的网站上显示他们最新的推文。代码如下:

我现在希望在Google的Blogger上对他们的博客做类似的事情。我曾假设有一种方法可以使用我的Google API密钥和秘密来读取博客的公开内容，而不需要用户进行身份验证。我只需要博客标题和日期，这样我就可以链接到博客网站。但是我花了24小时在互联网上搜索，找不到任何只用密钥和秘密获得访问令牌的例子。

使用Google API SDK，我已经得到了下面的代码，但找不到一种方法来获得访问令牌而不让用户进行身份验证。任何建议都很感激-感觉我的头撞到了墙上!很高兴采取任何方法-我只是想在我正在建设的网站上获得一些博客内容…

Authenticate with Twitter:

        var oAuthConsumerKey = _key;
        var oAuthConsumerSecret = _secret;
        var oAuthUrl = "https://api.twitter.com/oauth2/token";
        // Do the Authenticate
        var authHeaderFormat = "Basic {0}";
        var authHeader = string.Format(authHeaderFormat,
             Convert.ToBase64String(Encoding.UTF8.GetBytes(Uri.EscapeDataString(oAuthConsumerKey) + ":" +
                    Uri.EscapeDataString((oAuthConsumerSecret)))
                    ));
        var postBody = "grant_type=client_credentials";
        HttpWebRequest authRequest = (HttpWebRequest)WebRequest.Create(oAuthUrl);
        authRequest.Headers.Add("Authorization", authHeader);
        authRequest.Method = "POST";
        authRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
        authRequest.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
        using (Stream stream = authRequest.GetRequestStream())
        {
            byte[] content = ASCIIEncoding.ASCII.GetBytes(postBody);
            stream.Write(content, 0, content.Length);
        }
        authRequest.Headers.Add("Accept-Encoding", "gzip");
        WebResponse authResponse = authRequest.GetResponse();
        // deserialize into an object
        string objectText;
        using (authResponse)
        {
            using (var reader = new StreamReader(authResponse.GetResponseStream())) 
            {
                objectText = reader.ReadToEnd();
            }
        }
        // objectText is JSON and contains access_token

认证博客??

    private bloggerTest()
    {
        // Register the authenticator.
        var provider = new NativeApplicationClient(GoogleAuthenticationServer.Description)
        {
            ClientIdentifier = _key,
            ClientSecret = _secret
        };
        var auth = new OAuth2Authenticator<NativeApplicationClient>(provider, GetAuthorization);
        // Create the service.
        var service = new BloggerService(new BaseClientService.Initializer()
        {
            Authenticator = auth
        });
        var result = service.Posts.List(_blogID).Fetch();
    }
    private IAuthorizationState GetAuthorization(NativeApplicationClient arg)
    {
        var state = new AuthorizationState(new[] { BloggerService.Scopes.BloggerReadonly.GetStringValue() });
        // I am stuck here!
    }

XDocument feed = XDocument.Load(rssUrl);   //rssUrl is the URL to the rss page that (most) blogs publish
SyndicationFeed sf = SyndicationFeed.Load(feed.CreateReader());
foreach (SyndicationItem si in sf.Items)
{
    ..you've now got your feed item...
}
